TCustomVariantType.Cast

Cast a custom variant to another type

Declaration

Source position: variants.pp line 200

public 
  procedure Cast(var Dest: tvardata; const Source: tvardata);  Virtual;

Description

Cast is called when a variant value Source is cast to a custom variant Dest. Descendents must override this method to provide the desired conversion behaviour.

The TCustomVariantType implementation of Cast calls CastTo on the source variant with as destination type the custom variant type.

Errors

If the variant type cannot be cast, an exception is raised.
